Impeller improves suction characteristics in high-pressure pumps

Tuesday, July 24th, 2018 von admin

KSB experts developed a special impeller for its Movitec multistage high-pressure pumps. This new impeller significantly improves these pumps’ suction characteristics (NPSH value).

It proves its worth particularly in applications with critical inlet conditions (e.g. boiler feed applications) as well as applications in which the pump is required to take in water from low-lying tanks or at higher temperatures. Under these conditions, a pressure drop in the intake area may cause cavitation to occur in the first pump stage. This can result in excessive wear of pump parts or motor bearings as well as a reduced service life of the pump due to damaged parts and an unbalanced hydraulic system.

The new impeller is offered as an alternative to the standard product.

Sulzer: Key Safety Pumps for the Kilpilahti Power Plant

Thursday, May 4th, 2017 von admin

Sulzer has secured two pump orders from Técnicas Reunidas for the Kilpilahti combined heat and power plant in Porvoo, Finland. The plant is currently owned by Neste, Veolia, and Borealis. The orders comprise 12 feedwater pumps and 11 Ahlstar pumps, which will be manufactured by Sulzer in Germany and Finland respectively.

Técnicas Reunidas is acting as an engineering, procurement, and construction (EPC) contractor for the construction of the Kilpilahti project. Three new steam generators with a capacity of 450MW of thermal heat and a power output of around 30MWwill be installed. The power plant will comply with the latest environmental regulations, including the European Commission’s Industrial Emissions Directive (IED).
